In this paper, we address the questions of whether early family trajectories of parents are reflected in childbearing teenagers, and how socio-economic and family background factors impact these intergenerational correlations. We use within-dyad sequence analysis to examine combined marital and childbearing trajectories, up to age 30, of two generations of a representative sample of childbearing teenagers born between 1975 and 1985 and their progenitors, drawn from the Swedish population register data. We find evidence for within-family persistence of early family trajectories, with better matches across family state sequences for dyads composed of childbearing teenagers and their parents, than for dyads composed of childbearing teenagers and parents of random birth cohort peers. Regression analysis shows that these intergenerational associations are stronger and occur among later-born siblings from non-traditional family backgrounds, and among families with lower socio-economic backgrounds. This study fills gaps in the knowledge of intergenerational family life course dynamics beyond the early parenthood event.

在本文中，我们解决了以下问题：父母的早期家庭轨迹是否反映在育龄青少年中，以及社会经济和家庭背景因素如何影响这些代际相关性。我们使用二元组内序列分析来检查 1975 年至 1985 年之间出生的育龄青少年的两代代表性样本及其祖先的合并婚姻和生育轨迹，直至 30 岁，这些样本来自瑞典人口登记数据。我们发现了早期家庭轨迹在家庭内持续存在的证据，与由育龄青少年和随机出生同龄人的父母组成的双人组相比，由育龄青少年及其父母组成的双人组在家庭状态序列中的匹配更好。回归分析表明，这些代际关联更强，发生在来自非传统家庭背景的晚出生的兄弟姐妹和社会经济背景较低的家庭中。这项研究填补了在早期为人父母事件之外的代际家庭生活过程动态知识方面的空白。
